Answer: 2/3
Explanation:
Number of red cubes = 2
Number of green cubes = 1
Total cubes in the bag = 3
The question relates to a probability with replacement. The probability of getting two reds will be the probability of picking red the first time multiplied by the probability of picking red the second time. This will be:
= 2/3 × 2/3
= 2/3
